Using the BBB method, this is the first year I have had perfect pool water all summer, even with extremely hot weather. No sign of algae even once! the only issue I had was once my daughter and friends used so much sunblock lotion and it caused the water to turn a bit cloudy, but was back to normal within a day...

I have not had to shock but once (for the lotion issue only).

I am so glad I found this group. now I do not know what to with the chemicals I have I no longer need. I have not been able to sell them (cheap) at garage sale.
